PROBLEM TO BE SOLVED: To provide a bearing structure of a motor by which the number of parts can be decreased, a miniaturized, motor and the cost of the motor can be reduced. SOLUTION: An inner ring 14b for ball bearings 14 is inserted into a shaft 12. Snap rings 19 are fitted into a peripheral groove 20 of the shaft 12. The outer circumferential surfaces of sections protruded from the peripheral groove 20 are abutted against the chamfering section of one side face of an inner ring 14b in the snap rings 19, and the inner ring 14b is retained so as not to be moved to the inside more than that. A fan insert member 21 is abutted against the external side face of the inner ring 14b. The inner ring 14b of the ball bearings 14 and the insert member 21 are held by a nut 24 and the snap rings 19 by clamping the nut 24. |
